3

Set T90 to 10 seconds.

4

Observe the display.

5

Set the pressure regulator on the gas cylinder to 0 bar and observe the measured
values.

6

Set the pressure on the pressure regulator to approx. 3 bar and observe the
measured values.

7

If zero is not reached within a certain time (depending on the T90 settings of the
measuring system), increase the pressure in steps until zero is stable.

8

When zero is stable, reduce the pressure in small steps again and observe the
display.

9

Increase the pressure again by 0.5 bar when the display rises above zero again.

10 Note the values on gauges 1 and 2.

NOTE

These values can be used later as prelimiinary pressure settings.
The correct test gas pressure is typically between 4 mbar and 10 mbar above the
process pressure.

11 Reset the T90 value.
12 Close the shut-off valve and gas cylinder.
13 Return to measuring mode.

7.11.3

Automatic SPAN test

The calibration test is carried out with different equipment depending on customer
requirements.

NOTICE

Valve control as well as triggering a SPAN test must be carried out with an automatic
calibration test unit from the customer.

Equipment for an automatic SPAN test

Low requirements

1

Determine the pressure settings required before starting the test.

2

Connect test gas via solenoid valves to the GPP inlet.

3

Use a gauge to set the preliminary pressure settings on the gas cylinder.

NOTE

Changes to the flow resistance in the filter can cause pressure rises or

drops that then influence measuring precision (gas law).

High requirements

1

Connect test gas via solenoid valves and adjustable pressure regulator to the GPP
inlet.

b

The pressure regulator serves to keep the pressure in the measuring cham‐
ber constant.

b

The control signal is generated by comparing the fine pressure measurement
in the chamber with a value previously specified.

NOTE

Changes in the filter material influence the time required for purging.
